No, it doesn't. It shows that people are using the term "gamer" too loosely. People have been playing solitaire on their computer for decades. They were never considered gamers back then, so what's changed?

Gamer has always meant someone who had more than a passing interest in games. Not just in one game, not in a game every now and then. In GAMES. In GAMING. All this crap about how casual "gamers" still count as "real" gamers is just that: crap.
